It is principal part sectional drawing which shows the junction part of FIG.4 and FIG.5. The casing device shown in FIG. 1 is an example in which the casing of the present invention is used as a control panel, and the overall appearance is the same as the conventional one. The casing device 100 is made of an angle material or the like. A rectangular first panel (bottom plate member) 1 supported on the formed pedestal 101, and two second panels (side walls) extending parallel to each other upward from the left and right side end portions of the first panel 1 Member) 2, a rear door 3 connected to the first panel 1 and the second panel 2, a front door 4 that closes an opening on the front face so as to be openable and closable, and a ceiling member 5. Each member is made of a metal material such as a steel plate.

  Inside the second panel 2, a fixing bracket 102 having a substantially C-shaped cross section generally called a pre-chan is attached in the horizontal direction by a rivet or the like, and a vertical unit mounting bracket 103 is attached to the fixing bracket 102. Is attached by a mounting screw (not shown). The first panel 1 used as a bottom plate member is formed by bending reinforcing portions 11 on four peripheral sides or required side portions by sheet metal processing, and the second panel 2 used as a side wall member is similarly bent. The reinforcing part 21 is formed. The first panel 1 and the second panel 2 are mutually connected by using an L-shaped coupling member 6 (shown in FIG. 2) and a fastener 7 such as a rivet (shown in FIG. 6) which will be described later with reinforcing portions 11 and 21. It is configured to be joined to each other at a predetermined portion to form a housing, and to house an electronic device or an electric device inside.

  As shown in FIGS. 2 and 3, the reinforcing portions 11 and 21 are reinforcements that form a joint side portion F that extends in the front-rear direction and fixes the first panel 1 and the second panel 2 at right angles to each other. The parts 11A and 21A and the front door 4 or the rear door 3 are attached, and there are reinforcing parts 11B and 21B that are attached to the inside so as to contain the coupling member 6 and are firmly fixed to each other to form an opening. Reinforcing portions 11B, 21A, and 21B are substantially U-shaped in cross section except for the notch for inserting the coupling member 6, and the reinforcing portion 11A also excludes the notch for allowing the coupling member 6 to be inserted. Although most of the cross section is formed in a key shape or a crank shape, the shape and structure are not particularly limited to those shown in the drawings. The L-shaped coupling member 6 is formed to have an L-shaped plate surface portion 6 a having a predetermined width W, and a side 61 of the L shape extending in the horizontal direction from the corner portion 6 c contacts the upper surface of the first panel 1. The bent portion 61a is formed, and the other side 62 of the L-shape extending vertically upward from the corner portion 6c is formed with a bent portion 62a that is in contact with the inner side surface of the second panel 2. The cross-sectional shapes of the portions 61a and 62a are substantially L-shaped.

  One of the typical features of the present invention is a reinforcing portion in which the corner portion 6c of the L-shaped plate surface portion 6a of the coupling member 6 serves as a joint side portion F between the first panel 1 and the second panel 2. 11A, the back surface portion of the reinforcing portion 11B disposed at the corner corner C of the 21A and having one side 61 of the L-shaped plate surface portion 6a extending from the corner corner C in a direction perpendicular to the joint side portion F of the first panel 1 The other side 62 of the L-shaped plate surface portion 6a is contacted along the back surface portion of the reinforcing portion 21B extending from the corner portion C in the direction perpendicular to the joint side portion F in the second panel 2, The fastening hole A1 and the fastening hole B1, and the fastening hole A2 and the fastening hole B2 each formed of rivet holes are arranged at multiple points at the tip of the one side 61 and the other side 62 so as to be separated from the corner portion C or the corner portion 6c. Each point is fixed by a fastener 7 such as a rivet.

  Another one of the typical features of the present invention is that the coupling member 6 having the L-shaped plate surface portion 6a having a predetermined width W is provided at a plurality of positions from the outer end portion of the corner portion 6c of the L-shaped plate surface portion 6a. Of the fastening holes, the length L to the center of the fastening hole D (shown in FIG. 3) closest to the corner 6c is 5 times or more, more preferably 7 on both the one side 61 and the other side 62 with respect to the predetermined width W. It is a point that consists of more than twice. In addition, although the predetermined width W is not specifically limited, As a specific example in the housing | casing of a general electronic device, the thing about W = 25 mm-40 mm can be used, for example. Further, when the width of one side 61 is W1 and the width of the other side 62 is W2, W1 = W2 is usually sufficient, but they may be different from each other. For example, the length of one side 61 of the coupling member 6 is configured not to interfere with the opposite coupling member 6 (not shown) installed on the right side of the first panel 1.

  Moreover, although the number of the fastening holes showed the example of four places, it is good also as three places. If the number of fastening holes is two, the strength and reliability may be insufficient, which is not preferable. Moreover, although it is good if it is four or more places if necessary, since it does not increase so much that the effect is expected to increase in the ratio of the number of work steps and the number of parts, it is not desirable. Further, the width W of the coupling member 6, the length L, the length of one side 61 and the other side 62, the number of fastening holes, and the like are appropriately within the above ranges according to the size of the casing and the required seismic strength. Can be changed. In addition, although the corner corner part C of the lower left of the housing | casing of FIG. 1 was demonstrated, it is comprised similarly about another corner corner part. The configurations shown in FIGS. 2 to 6 are preferably installed at all eight corners of the casing device, but at least the strength required to be normally required by installing them at four locations on the lower end side. It is also possible to provide a casing device that clears the above. In addition, when installing the coupling member 6 in the upper part of a housing | casing apparatus, it can comprise similarly by replacing the above-mentioned 1st panel 1 with the ceiling member 5. FIG.

  In order to assemble the casing device from each member as described above, as shown in FIGS. 2 and 3, one side 61 of the coupling member 6 is inserted into the back side of the reinforcing portion 11B of the first panel 1, and the other side 62 is inserted into the back side of the reinforcing portion 21B of the second panel 2, and the fastening hole A1 of the first panel 1 and the fastening hole B1 of the coupling member 6, and the fastening hole A2 of the second panel 2 and the coupling member 6 The fastening holes B2 are made to coincide with each other, and a fastener 7 such as a rivet (FIG. 6) is inserted to firmly join the coupling member 6 and the first panel 1 and the coupling member 6 and the second panel 2 by plastic deformation. It should be noted that the reinforcing portion 11A and the reinforcing portion 21A, which are the joint sides F between the first panel 1 and the second panel 2, are also provided at a plurality of locations separately by the fastener 7 before or after the joining by the connecting member 6. Join with. By similarly joining other panels as well, a casing device in which the panels are firmly joined as shown in FIGS. 4 and 5 is obtained.

  As described above, in the first embodiment, the fastening holes A1, B1, A2, and B2 of the first panel 1, the second panel 2, and the coupling member 6 are arranged at multiple points, and fastening portions are formed. By installing it at a position away from the corner C by a predetermined dimension, for example, the fastener 7 deforms beyond the elastic limit at the corner C where stress concentration occurs in the seismic test, and the fastening hole deforms due to deformation or breakage or vibration. Then, problems that occur in the housing structure, such as the fastener 7 coming off, can be prevented, and a highly reliable structure can be obtained. Further, the coupling member 6 couples the first panel 1 and the second panel 2 to each other, and there is no portion to be coupled across three parts, leading to a reduction in work man-hours. Further, since the panels are connected by the coupling member 6, for example, the vibration received from the first panel 1 is transmitted to the second panel 2 via the coupling member 6 and the fastener 7. Is generated, the response magnification transmitted to the unit installed inside can be reduced, and the resonance frequency can be increased.

  An experiment was performed in which the casing device of the first embodiment configured as described above was compared with a welding casing (not shown) of the same size in which the panels were joined by welding. As a result, in the seismic test under the condition that the mass of the internally mounted equipment is maximized, the resonance frequency in the left-right direction (width direction) when viewed from the front is compared to the welded casing 4 Hz. It is confirmed that both the case device 1 has an improvement of 5 Hz, and the longitudinal direction (depth direction) is improved to 26.7 Hz in the case device of the first embodiment, compared to the welded case 16.7 Hz. It was done. Also, the response magnification was improved to 4.5 times in the case device of the first embodiment compared to 10.6 times in the welded case at the upper position of the case.

  As described above, according to the first embodiment, one side 61 of the coupling member 6 having the L-shaped plate surface portion 6a having the predetermined width W is connected to the second panel in the first panel 1 from the corner C of the housing device. Abutting along the reinforcing portion 11B extending in a direction orthogonal to the joining side F of the panel 2 and the other side 62 of the L-shaped plate surface portion 6a from the corner C to the joining side F of the second panel 2 The one side 61 and the other side 62 of the coupling member 6 are spaced apart from each other by a predetermined distance from the corner portion 6c and dispersed in the longitudinal direction. Since at least three fastening holes B1 and B2 are fastened to the corresponding reinforcing portions 11B and 21B, stress concentration generated at the corners can be avoided and the fastening points are dispersed. The load on the fastening part is also distributed, Housing device is obtained having a sufficient rigidity to channel cross get firmly bonded required earthquake resistance.

  Further, since no adhesive is required, the management of the adhesive and the bonding work are not required, the assembly time is shortened, and a casing device with little variation in bonding strength can be obtained. Further, since the coupling member 6 attached to the back surface of the U-shaped reinforcing portions 11B and 21B can be included in the sheet metal shape of the reinforcing portions 11 and 21, the appearance is not impaired.
